Class Xor

  • All Implemented Interfaces:
    Scalar<Boolean>
    public final class Xor
extends ScalarEnvelope<Boolean>
    Logical exclusive or. Returns True when an odd number of elements have value true, otherwise return False.

    This class could be also used for matching multiple boolean expressions:

    new Xor( new True(), new True(), new True() ).value(); // the result is true new Xor( new True(), new False(), new True() ).value(); // the result is false

    This class implements Scalar, which throws a checked Exception. This may not be convenient in many cases. To make it more convenient and get rid of the checked exception you can use the Unchecked decorator. Or you may use IoChecked to wrap it in an IOException.

    There is no thread-safety guarantee.
